609169 divided by 13 
The aim is to understand the frequency of 13 in 609169.

On to step 1:
If we divide 6 by 13, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 13

Going ahead to step 2:
60 divided by 13 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 52 from 60 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 13

On to step 3:
13 can be fit into 89 6 times, resulting in a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
The remainder is 11 after subtracting 78 from 89.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 13

Moving on to step 4:
13 goes into 111 8 times with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 468.0
Subtract 104 from 111 to get 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 13

Going ahead to step 5:
When dividing 76 by 13, we get 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 4685.0
If we subtract 65 from 76, we get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 13

Let's proceed to step 6:
13 goes into 119 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 46859.0
The remainder is 2 after subtracting 117 from 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
13 can be fit into 20 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 46859.1
Subtract 13 from 20 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
The number 13 fits into 70 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 46859.15
Subtract 65 from 70 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 13, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 46859.153
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 46859.1538
Subtracting 104 from 110 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
If we divide 60 by 13, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 46859.15384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
80 divided by 13 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 46859.153846
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
When dividing 20 by 13, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 46859.1538461
Subtract 13 from 20 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 46859.15384615
If we subtract 65 from 70, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 46859.15384615, and the remainder is 5e-09.
